So long as you get a sample of eve ocean back to Kerbin, the rover method is fine. It might even make for a smaller ascent. If you can brave the day-long burn time, a mechjeb+wing assisted Ion launch may be superior.

The rules state that you can only use one launch. If you wish to leave fuel in Eve orbit, that is fine, so long as it is sent up there in the same launch as your probe.

Yes, that may be so, but your craft should be engineered to not rely on so many gravity assists...

Raising your periapsis from 40km to 70km will cost barely 50m/s, as another said, you can do it with RCS. Interestingly, you can also probably do it with ions.

Actually, I've seen many craft deliver manned pods to Kerbin from Eve. I'm only asking for a probe core, which is only 40kg.

There's basically four photo requirements: * On runway * At KSC's antipode with half fuel or less. This means it counts if you've only used a millilitre of fuel. * Landed safely at sea * Landed safely on land, far enough from KSC, such that I can see that you would not have simply taxi-ed to your landing spot.I used the second runway island as an easy example for such an example, the intervening sea prevents taxi-ing.

I've updated the OP to state the allowed mod packs; as the old SEAV challenge allowed mods too. There will be no score loss, I'll only state which mods were used for each entry.

Some sort of have. Their destination was the moon, but it was a flyby, and some of those crafts were slingshotted entirely into solar orbit.

Yes, that would also work, and your design may use it. A rocket APRARS ma be heavier than a jet one, so keep that in mind.

Luxury. We had to climb a tree and light the bottom on fire and pretend we were on a failing rocket.

If they're kerbals, they must have some pretty good camoflage... And good interuniversal travel technology...

Well, there was this one guy... That was a joke, I'm an atheist. Although maybe misotheist is more apt...

This challenge is to create a plane/rocket/car (VTOL or HTOL or any variant) that can hold four kerbals, such that it has one pilot and room for the crew of a 3 - man mission. It must: Be able to circumnavigate Kerbin without re-fuelling (ie travel to KSC's antipodal point and return) - even if this occurs at 40km and 2km/s. Alternatively, it can travel to this point via a sub-orbital hop. [*]Be able to land on land or water, without losing parts. [*]Be able to return to KSC, not necessarily the Runway. [*]Be reusable, in that no parts are destroyed or jettisoned. [*]have adequate infrastructure to allow astronauts to climb into the cockpits It may: Land via parachutes, so long as one of the passangers can repack them. Scoring: Entries will be scored on the mass of the craft. To qualify, you need only an image of the plane at the runway, the plane at roughly KSC's antipode, showing the fuel levels to be half or less, the plane landed on the island of the second runway (not necessarily at that runway), and the plane landed on water. Due to the water requirement, your design may need to be a VTOL or VTOL capable.

You may want to alter the .cfg such that the electricity demand and fuel consumption go up 100x as with the thrust, with the Isp dropping 15%, so this won't be as painful.

I think that the whole point of a colony drop is to destroy the colony or destroy something on the surface.

I think that's Jool. I've gone to -600m and survived. Surprisingly by impacting the ocean at 1km/s.

When you get below 1338m, you overheat and die.

With ion engines, as you must burn significantly before/after periastron, the required delta-v goes up maybe 10%.

If you don't mind a little .cfg editing, you can change Xenon's flow to be the same as the ordinary fuel; such that you can have an asparagus ion craft.

Well, I destroyed the Dreadnought... The old fashioned way!

You need sufficient power to operate your ion engines at full throttle pointing retrograde (or NML +/-, just not out of that plane), at Kerbin's height or less. So, a total of at least 15 units per second.

Why do you want to send 100 tons to LKO?

Your challenge is to build a craft with the most delta-v you can muster, and simply deliver it to solar escape. Rules: All parts allowed Mechjeb allowed Final craft must be placed in an 'orbit' of eccentricity 1 or more with respect to the Sun Craft using ion engines must have a sufficient power source. (Power supply sufficuent to operate at full throttle pointing retrograde at Kerbin's height or less). Notes: Entries will be ranked on delta-v remaining in solar Escape Orbit Entries must include a pic of the craft on the launchpad and (any point) in solar escape. Mechjeb is recommended, at least to tell you how much delta-v is remaining. Dv to LKO is about 4.5km/s. Dv to Solar Escape from LKO is about 2.9km/s. Leaderboard: Istas - 23.3 km/s I have completed this, with a final craft having a delta-v of 13.5km/s. For me to best this, I would need to use either Mainsails to haul a bigger payload, or use an 'Ion-Sparagus' design.

I think Nhnifong (or whatever his name is) created a debris maker, of a Stayputnik covered in antennas, with a seperatron pointing into the Stayputnik. Staging causes the Stayputnik to overheat, releasing the antennae.

Change the .cfg to remove the fairing.
